Context
Context. A store sells e-books, gift cards or workshop places, on their own or beside goods it posts. Nothing goes in a parcel, but every order still gets a fulfilment, and a checkout needs a selected shipping rate on it before it can be paid. A shipping method with Nothing to ship switched on covers these products: its free rate is chosen for the shopper, the fulfilment is marked delivered as soon as the order is paid, and with inventory tracking on the products need no stock.
